Complete Questions and Guide Answers
100% Verified Graded A+
1. VESCP
Answer: Virginia Erosion and Sediment Control Program
- Administered by counties/cities (must), towns (may)
- MUST BE APPROVED
2. Minimum Standard 1
Answer: Stabilization
permanent or temporary soil stabilization shall be applied to denuded areas within seven days after final grade is reached on any
portion of the site; temporary soil stabilization shall be applied within seven days to denuded areas that may not be at final grade but
will remain dormant for longer than 14 days; permanent stabilization shall be applied to areas that are to be left dormant for more than
,one year
3. Site NOT at Final Grade
Answer: - stabilize in 14 days
- temporarily seed
- mulch
- permanently stabilize if dormant > 1 year
4. Site at Final Grade
Answer: - stabilize in 7 days (recommended immediately)
- permanently or temporarily seed and mulch
- mulch/matting/straw
5. Minimum Standard 2
Answer: Stock Piles, Waste and Borrow Areas
during construction, soil stock piles and borrow areas shall be stabilized or protected with sediment trapping measures
mulch prevents erosion by protecting the surface from raindrop impact and silt fence intercepts and detains from disturbed areas
6. Minimum Standard 3
, Answer: Permanent Vegetation
permanent vegetation cover shall be established on denuded areas not otherwise permanently stabilized (permanent vegetation shall
not be considered established until a ground cover is achieved that is uniform, mature enough to survive, and will inhibit erosion
*there is no % associated with this*)
reduce erosion and decrease sediment yield from disturbed area
this is the standard used to verify that a site is ready for release of bonds or surety
7. Minimum Standard 4
Answer: First-Step Measures
Sediment basins and traps, perimeter dikes, sediment barriers and other measures intended to trap sediment shall be constructed as a
first step in any land-disturbing activity and shall be made functional before upslope land disturbance takes place
a certain amount of initial land disturbance may be required to provide access for equipment to install the perimeter controls, but site
clearing and grading should be kept to a minimum until the perimeter controls are in place
intercepts and detains small amounts of sediment from disturbed areas during construction operation to prevent sediment from
, leaving the site and decrease velocity of sheet flows and low-to-moderate level channel flow
8. Perimeter Controls
Answer: assures that sediment does not leave the perimeter of the land-disturbing area once
site clearing, grading, and construction commences
Examples silt fences, sediment traps, sediment basins, construction entrance, temporary diversions, diversions
9. Minimum Standard 5
Answer: Earthen Structure Stabilization
stabilization measures shall be applied to earthen structures such as dams, dikes, and diversions immediately after installation
reduce erosion and sedimentation and reduce damage from sediment and runott to downstream or ott-site areas
10. Minimum Standard 6
Answer: Trapsand Basins
sediment traps and basins shall be designed and constructed based upon the total drainage area (not just disturbed area) to be
served by the trap or basin
11. Sediment Traps
